What is convection?
400
The way marble statues or memorials release carbon into the atmosphere.
What is neutralizing acid rain?
400
The process through which bacteria break down nitrates and release nitrogen gas into the atmosphere.

500
How the carbon dioxide and oxygen cycles are related.
What are photosynthesis and cellular respiration?
500
The process by which plants take in nitrogen from surface water or oceans.
